Let's not give them credit for having two subsystems called 'control panel' and 'settings'. That it happened even once is an embarassment, and I think they started that with Windows 8.
That is indeed when it is started, but that's the one and only time - it's just that this transition is still ongoing, after 11 years. By now everything that a casual user might need is in the "new" settings, and much of the advanced stuff is as well, but it's not complete.
